Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

Claystone vs Travertine Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Claystone vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Travertine. Learn more about Claystone vs Travertine in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Claystone and Travertine, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
More about Claystone and Travertine
Here you can know more about Claystone and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Travertine consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Claystone is Rough and Dull and that of Travertine is Fibrous. Properties of rock is another aspect for Claystone vs Travertine. The hardness of Claystone is 3.5-4 and that of Travertine is 3-4. The types of Claystone are Claystone whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Travertine is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
